Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed February 7, 1916. Serial No. 76,677.

To all whom it may concern:

Be it known that I, RoY T. AXE, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Windin -Roller, of which the following is a specification.

This invention relates to Winding rollers and has for its object a particularly simple and eificient'construction whereby a chain or cable which winds on the roller, is readily attached to the roller which chain or cable usually supports a window or other means; and the invention consists in the combinations and constructions hereinafter set forth and claimed. 7

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. I

Figure '1 is an elevation, partly broken away, of'a roller embodying my invention, the end portions of a chain attached to the roller being also shown, one end being'shown as attached thereto and the other as de tached therefrom.

Figs. 2 and 3 are sections taken respectively on lines 2-2 and 33, Fig. 1, the end of the chain which is shown as detached in Fig. 1, being shown as attached to the roller in Fig. 3.

Fig. 4 is a detail view of the coupling piece between one end of the chain and the roller.

1 designates the roller which may be of any suitable form, size and construction, said roller including a sheet metal tube and having the usual trunnions or axles 2, 3 at its opposite ends, one of which is rigid with the roller and the other of which is connected to a torsion spring not shown, located within the roller as willbe understood by those skilled in the art. 7

The tubular body of the roller 1 is here shown as formed with an opening or openings therein near opposite ends thereof as the slots 4:, 5 and also usuallywith tongues, 6, 7 which tongues are struck up from the body of the roller 1 when the slots are formed, that is, the slots are left in the 'roller after the tongues 6, 7 are struck or cut out. Preferably, these slots and tongues extend in a direction circumferentially of the roller instead of lengthwise thereof- 8 designates a cable, the opposite ends of which are secured to the roller and the intermediate part of which is usually secured to a window or other part to be raised or lowered or counterbalanced as will be understood by those skilled in the art.

Each end of the chain or cable 8 is formed with means cXtending into the slots 1, 5 respectively, and havinga cross bar interlocking with the contiguous part of the tube of the roller 1 on opposite sides of the slots 4, 5, after the cross bar is interlocked with the tube, the tongue 6 or 7 which normally occupies the position shown in Fig. 3, is

bent into the position shown in Fig. 2 to' hold the said means at the end of the chain or cableS from undue movement in the slot 1 or 5'.

upon itself to bring eyes 9 at opposite ends of the link into alinement for receiving the intermediate or looped portion 10 of the nextlink as will be understood by those skilled-.inthe art. When the chain is com-- plete the eyes 9 of one end link are located at the extreme end of the chain while the loop 10 of the other end link is located at the other extreme end of the chain. Therefore, when a continuous chain is used different forms of coupling means must be provided. V a

The coupling means here shown are T- shaped and the T-shaped means connected to the end link in which eyes 9 are in alinement at the extreme end of the chain, consists of a strip 11 having laterally extending heads 12 at its opposite ends, one of these heads being passed through the alined eyes 9 of the end link and the strip being then bent upon itself bringing the heads The T-shaped means at the other end of V of the chain includes abar 13 passed through the loop portion 10 of the last link at the said end of the chain, this bar having enlargements 14 at its opposite ends which pass into the slot 5 and interlock with the roller 1 on opposite sides of the slot 5 in a manner similar to the engagement of the heads 12 With the roller 1.

After the T-shaped means are located-in the slots 4, '5, the tongues 6, 7 are bent into the position shown in Fig. 2, so that unin tentional detachment of the chain from the roller is prevented.

This means for attaching the chainsto the roller is particularly advantageous in that it is simple in construction, economical in manufacture and provides for the ready ren' oval and replacement of the chain When necessary. 7

What I claim is: V V l. The combination of a Windingroller comprising tube having a tongue struck therefromforming a slot, and a cable for and a cable for Winding on the roller having means: extending into the slot and a cross bar of less length than the length of the slot and :of greater, length than the Width of the. slot whereby the cross bar can be inserted through the slot into the cavity and turned. to interlock therein, and extend beyond the sides of the slot and engage theainternal face of the roller on opposite purpose set forth.

tion of the cable extending through the slot to prevent disengagement of the cable ifror-n the roller and hold-ingthecross bar from twisting into a position extending length- Wise of the slot, substantially as and for the purpose described. 3. The combination of a Winding roller comprising 'a tube having a tongue struck therefrom forming a slot a cable Winding on the roller and having means at one end extending into the slot, said means comprising a cross bar located in the roller and the cross bar interlocking with the portions of the roller on oppositesides of the slot, and the tongue being bent into position topartially close the slot andhold the said means from removal, substantially as and for the 4-. The combination of comprising a tube having a slot formed therein extending in av circumferential direction thereof, and a cable winding on the roller, and having means at one end extending through tl-reslotland including a cross bar located in the roller the cross bar extending lengthwise: of the rolleriand. on 0pe posite sides of the slot and interlocking with the contiguous portions of the roll'er,-' suba Winding roller stantially as and for the.- purpose-described.

In testimony W-hereofl have hereunto signed my name at Syracuse, in thecounty of Onondaga,v and Stateof New York this 20th day-.ot January,- 19-16.
